Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, the present invention includes the chair back 1 and bench 3, utilize chair back control apparatus 2 to connect between the chair back 1 and bench 3, bench 3 inside is provided with bench control apparatus 4.
As shown in Figure 2, chair back control apparatus 2 comprises strut member 8, pipe link 9, briquetting 7, cluster gear 11 and the first spring 10.Utilize cluster gear 11 and the first spring 10 to be connected between strut member 8 with pipe link 9, briquetting 7 is installed on the both sides of strut member 8.Strut member 8 comprises fixing curved bar 8-1 and is located at the installation ring 8-2 at fixing curved bar 8-1 two ends.Fixing curved bar 8-1 is provided with bolt mounting holes, and bolt mounting holes, for installing the chair back, makes the chair back be connected with strut member 8.The centre of installation ring 8-2 has been provided with separates catch 8-5, and the side and the installation ring 8-2 that separate catch 8-5 form briquetting mounting groove 8-4, and another side and installation ring 8-2 form the first gear mounting groove 8-3.The two ends, left and right of pipe link 9 are respectively equipped with the second gear mounting groove, and left end is the second gear mounting groove 9-1, the second gear mounting groove structure of right-hand member and the identical of left end.The interlude of pipe link 9 is provided with fixed block 9-2.Fixed block 9-2 is for installing fixed connecting rod 9 in bench.Cluster gear 11 and the first spring 10 are installed in the space that the first gear mounting groove 8-3 and the second gear mounting groove 9-1 formed.
The degree of depth of the first gear mounting groove 8-3 is less than the degree of depth of the second gear mounting groove 9-1, like this by pressing, just can realize being separated between cluster gear 11 with the first gear mounting groove 8-3.
Separate catch 8-5 and be provided with bayonet socket 8-6; Briquetting 7 lower end, left side is provided with snap fit 7-1; Snap fit 7-1 extends in the first elastic claw wheel mounting groove through bayonet socket, and briquetting 7 is installed in briquetting mounting groove 8-4.Briquetting 7 lower end, right side is provided with snap fit; Snap fit extends in the first elastic claw wheel mounting groove through bayonet socket 8-6, and right side briquetting 7 is installed in briquetting mounting groove.
Cluster gear 11 side is planar structure 11-1, and opposite side is provided with positioning groove 11-2.First spring 10 one end is installed in the positioning groove 11-2 of cluster gear 11, and the other end is installed in the second gear mounting groove 9-1.
Under state of nature, the cluster gear 11 at pipe link 9 two ends, under the effect of the first spring 10, is placed in the region of the first gear mounting groove 8-3 and the second gear mounting groove 9-1 formation.The snap fit 7-1 of briquetting 7 lower end through bayonet socket and cluster gear 11 inconsistent.Be provided with sliding stroke section between snap fit 7-1 and briquetting 7 upper end, therefore briquetting 7 has mobile space, but can not depart from briquetting mounting groove 8-4.Under adjustment state, the briquetting 7 simultaneously pressing strut member 8 both sides is not in opposite directions let go, and now, the cluster gear 11 inconsistent with snap fit 7-1 and the first gear mounting groove 8-3 depart from, and such strut member 8 just can rotate freely, and indirectly drives the rotation of the chair back.When rotating to correct position, unclamp the briquetting 7 of both sides, cluster gear 11 return under the effect of the first spring 10, in first gear mounting groove 8-3 of cluster gear 11 playback, briquetting 7 is outwards moved by cluster gear 11 simultaneously, and such strut bar 8 is just fixed by cluster gear 11, and the chair back can not realize rotating.
As shown in Figure 3 and Figure 4, bench control apparatus 4 comprises the seat of honour 12, lower seat 14 and regulates disk 13.Be provided with manhole 14-1 in the middle of lower seat 14, regulate disk 13 to be movably installed in manhole 14-1.Utilizing between the seat of honour 12 with lower seat 14 regulates disk 13 to be connected.
As shown in Figure 5, disk 13 is regulated to comprise disk body 17, second spring 16 and pulling block 15.Second spring 16 is installed on the both sides of pulling block 15, and installs in notch 17-1 with the pulling block that pulling block 15 is installed on disk body 17 jointly.The end face of pulling block 15 is provided with clamping projection 15-1, and the lower end of pulling block 15 is provided with drag hook 15-2.As shown in Figure 4, the seat of honour 12 is provided with blocked hole with regulating the relative side of disk 13, and clamping projection 15-1 is corresponding with the position of blocked hole, realizes the connection of the seat of honour 12 and adjustment disk 13.Blocked hole on the seat of honour 12 has two, is respectively blocked hole 12-1 and blocked hole 12-2; Angle between two blocked holes is 180 degree.
As shown in Figure 1, the below of disk body 17 is provided with and installs slotted eye 5 and installation gap 6.As shown in Figure 5, pulling block is installed in notch 17-1 and is provided with spring card pole 17-2 and port 17-3.As shown in Figure 6, second spring 16 one end is fixed on spring card pole 17-2, and the other end is installed in the draw-in groove of pulling block 15 both sides.The drag hook 15-2 of pulling block 15, through port 17-3, is exposed to installation gap 6 place of disk body 17.
The seat of honour 12 and lower seat 14 are respectively equipped with reinforcing rib structure 12-3 and reinforcing rib structure 14-2.Ensure the working strength of bench.
Disk body 17 utilizes the installation slotted eye 5 below it to be fixed on perambulator car body, hold drag hook 15-2 on pulling block 15, make to draw fast 15 to move down, at this moment, clamping projection 15-1 is separated with the blocked hole of on the seat of honour 12, because disk body 17 is movably installed in the through hole 14-1 on lower seat 14, such bench just can revolve turnback to regulate centered by disk 13, then pulling block 15 is unclamped, pulling block 15 resets under the effect of the second spring 16, clamping projection 15-1 on pulling block 15 assigns in another blocked hole, and such bench is just fixed and can not rotates.
